South Korean singer-actress Yewon, or Kim Ye-won, is under increasing pressure to quit the popular television show “We Got Married” over her squabble with actress Lee Tae-im.

“We Got Married” is a popular MBC TV show that puts celebrities in a mock marriage situation. The show, now in its eighth year on air, is also attracting keen attention in Asia, with two global editions and one Chinese edition successfully launched.

The controversy over Yewon, which occurred about a month ago, was recently reignited after the footage of the squabble was posted on YouTube.

Although it was initially thought that Lee, 28, had picked on and sworn at the younger celebrity in a rant, the recently released video showed otherwise.

While filming a new variety show for MBC in which celebrities try to learn new skills, Lee quit the program after the incident was made known. Lee, however, cited personal and health reasons for the decision.

In the latest video, Yewon is heard speaking to Lee in informal language that might be seen discourteous.

In response, Lee berates Yewon with coarse language. After Lee is guided away from the scene by the production staff, Yewon is heard saying “that crazy bitch.”

The footage quickly went viral in Korea, and has given rise to numerous parodies.

As the news spread, the message board for “We Got Married” has been flooded with posts demanding Yewon to give a formal apology and quit the show.

MBC, the broadcaster in charge of the show, is attempting to verify the route through which the video was leaked and taking legal measures.
